4Beit knownthat I, ALPHA R. BEAL, a citizen ofthe United States, residing at Pittsburg, .in

'the county of Allegheny and State' of {Penn- Sylvania, have invented new and useful Improveniente in Price or Money Weight-Scales, of-which the following is a specification.

. This invention Vrelates to certain iniproven 1:., alsoprovide forA vlifting and sustaining the' ments the' .price or money weight-scale patentedtome June 6, 1899, No. 626,520; and one bjectgthereofis to provide an improved rollerconnection between the steelyard-rod' and beam 'and to provide improved carriage' locking-and releasing. mechanism. a

"A 'further'objecttis to reduce to aminimurn the-drag upofthe beam at the point of con `may belen the scale-platform. This f depression'fthetare-beam is accomplished auto matically by A' mechanism operating in con- Junction with the carriage-locking devices. I

"The invention consists in the novel features.

Referring to the drawings, Qrepresents the pillars, rising from `a base (not shown) and supporting supplemental base Vor pillar cap 3,

6 is the carriage, having. depending longitudinal flanges' 7, the latter grooved at 8,- complementary with greoves, `to form races 'for bearing-balls 9, wherebyvthecarriage is held against vertical displacement and may he moved as requiredwithout friction.

Secured in the supplemental base is rack l 10'and cooperating therewith is dog 11, se cured on rock-shaft 12, mounted in carriage 6. Also carried by said shaft is spindle-arm -13, preferably made integralwith or secured to dog l11 and revoluble on thisarrn. Also slidable thereon longitudinally is roller 14, which travels on the free longitudinal portion of the vertically-swinging bail 15,. having -inally raised by elongated spring 16, bearing Vat its free end on theunder side thereof and sing operstinghandles i?,

conneclock 3l the bearing. The upward pull 'of tare-beam rod 42 on the nose-iron concurrently with the unlocking of the carriage has the effect of lifting rod 34 and block 31, as above referred to,

thereby facilitating the adjustment of the computing-beam. If rod 34 were not confined on the nose-iron, said upward movement of the latter would be liable to disengage it from bearing 40.

Fulcrumed in the end of carriage 6 is lever 46, provided at its outer end with ring 47, which embraces the tapered weight poise 48 of the price-beam. The inner end of said lever'is formed with the laterally-extending foot 49, which projects beneath cam 50 on shaft 12, so that when the latter is oscillated by depression of handles 17, as when releasing the carriage for changingits adjustment, the lever 46' is oscillated and its outer ringcarrying end lifts poise 48. The beam thus lightened lowers with respect to its steelyardrod connection, irrespective of the position of sliding poise 25', and thus further provision is made for disengaging rollers 36 from the* beam-Scallops while' the 'beam is being set. Thus it will be seen that the carriage is unlocked, the tare-beam depressed, and the pendent weight of the com puting-beam raised, all by the oscillation of shaft 12 through the medium of handles 17, and that said parts are returned to normal position bythe action of a single spring. .Y

Steelyard-rod34 is provided withl a turnbuckle or sleeve 34', whereby its length may be increased or diminished, as may be requir to eect a proper adjustment. v

4 The scale reads and is operated in connection with the price and value indications in the same way as .the scale described in my former patent, and such description need not be here repeated.

While I have shown andl described my several improvements assembled in a perfected scale, I do not wish to be understood as conningmyself to their use conjointly, as they vmay be employed severally in. scales of the character described, or two. or more of said 'improvements may be used together to the n pendent weight-poise.`
